To all whom it may-concern.

Be it known that I, GEORGE W. MILLER, a citizen of the United States, residing at Waynesville, in the county of Haywood and State of North Carolina, have invented new and useful Improvements in Saw Clamps, of which the following is a specification.

This invention relates to saw clamps-and contemplates a novel construction in a device of this kind with which the saw can be conveniently associated and clamped while the teeth are being dressed or filed, theclamp being susceptible of pivotal movement so that the clamp and saw can be arranged at any desired angle. I

Another object of the invention resides tion will be better understood when the following detaileddescription is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed. Y W

In the drawings forming apart ofthis application, likenumerals of reference indicate similar parts in -the several views, and wherein:

Figure 1 is a side elevation of the device;

Fig. 2 is a view looking from the opposite side thereof;

Fig. ,3 is a sectional view taken on the line 33 of Fig. 1;

Fig. 4 is a sectional view taken on the line 44 of Fig. 1; v

Fig. 5 is an enlarged detail view of the main clamp adjusting device; and

Fig. 6 is a similar view of the means for adjusting the secondary clamp.

Referring to the drawings in detail, 10 indicates a supporting bar on which the clamping device is mounted for pivotal Application flledMay 23, 1923, Serial No. 640,934. Renewed July as, 1924.

The nature advantages of the inven saw CLAMP.

,being done or the saw arranged at an angle for the comfort of the operator. A thumb nut14= is threaded on one end of this element andwhen tightened holds the clamping device fixed with relation to the bar 10. The-opposed ends of the bar are serrated as at 16 and cooperates with the-teeth'or se'rrations 17 formedon the end members of thezclamp to assist in holding the parts fixed relatively, subsequent to the tightening of the nut lei. 1 1 The clamping device essentially embodies a pair of spaced U-shaped end members, and the corresponding limbs 18 of these members are connected by a stationary jaw in j the nature of a bar herein indicated'at ceive fingers 23 projecting from a rod .24: which' is journalled in the lower portions of the U-shaped end members as shown. These fingers 23 are flanged or headed at their outer ends, the flanges 25 being arranged between the end members of the clamp and the arms pivoted thereon to prevent casual separation of the parts. The rod 24 is provided with a handle or manipulating portion 26 at one end of the clamp so that the rod can be partially rotated in either direction as the occasion requires. Manifestlywhen this handle is moved downwardly the rod 24 is rotated moving the fingers through the slots of said arms in a direction that imparts pivotal movement to the arms for the pur pose of moving the jaw 20 into gripping relation with the jaw 19. Conversely, when the manipulating portion or handle 26 is moved upwardly, the movementof the various parts is reversed, thereby separating the'jaws 19 and 21 respectively.

Arranged between the end members of the clamp and beneath the jaws thereof is a secondary clamp for the purpose to be hereinafter described,tl1is clamp including asleeve like member 27 indented to slide upon the rod 24. Rising from the sleeve 27 is a standard 28 supporting at its upper end a fixed jaw 29, and rising from this jaw is a lug or extension 30 movable in a longitu- 'd-inal slot 31' formed on the underside of the fixed jaw 19. This-lug or extension 30 assist's in guiding the secondary jfawv in movement longitudinally of -the rod 24. Piv otedonthe standard 28 is the shank 32 ot a movable jaw 33, the latter mentioned jaw being mounted to move toward and away from the fixed jaw 29. The shank 32 is slotted as at 34 and receives a pin 85 eccentrically mounted upon the cam shaped lever 36 pivoted as at 37-. Obviously, when the lever 35 is moved downwardly, the movable jaw 29 ismoved into clamping relation 3 with the fixed jaw, and when the lever is lifted, these 'jaws are separated. a

In practice, the saw to be dressed or otherwise dealt with is arranged between the jaws 19 and 20 of the main clamp and also between the jaws of the secondary clamp just described. Piior ti) clamping the jaws of the secondaryv clamp the latter is moved along the rod 24 toodcupy the position adjacent one end of the device. With the saw clamped between the jaws of the respective Clamps, it is held rigid while the saw is being dressed or the like, it being inderstood that the entire clamping structure can be swung upon its pivotal connection with the supporting bar 10 to arrange the saw in any desired position" or degree of inclination. After that portion of the saw arranged be tween the main clamps has been properly dealt with, it is necessary to move the saw longitudinally through the clamp to arrange anotherportion .of: the saw will a .osition whereby it can be dressed. When t jaws 19 and QO of the, main clamp have been released, the secondaryelafii'p "still engages the saw and prevents it from falling out of the device and at the i-isame time provides an adjustable support for the saw where it can be moved between and longitudinally of the jaws of the main clamp.

While it. is believed thatgirom the foregoing description, the nature and advantages of the invention: will be readily a1 parent, I desire to have uii'd'ers tdod that I do not limit myself to what *ilhe shown and described and that seen changes may be resorted to v\ivhen d'si' fall within the scope of what is" claimed 4 Having thus described the invention, I claim; v g
